Full details

The complete detail of the most relevant notes is as follows:

  1. Update – Missing Authorization check in SAP CommonCryptoLib (3340576): SAP CommonCryptoLib does not perform necessary authentication checks, which may result in missing or wrong authorization checks for an authenticated user, resulting in escalation of privileges. Depending on the application and the level of privileges acquired, an attacker could abuse functionality restricted to a particular user group as well as read, modify or delete restricted data. CVSS v3 Base Score: 9,8 / 10 [CVE-2023-40309].
  2. Improper Access Control vulnerability in SAP Business One product installation (3355658): SAP Business One installation does not perform proper authentication and authorization checks for SMB shared folder. As a result any malicious user can read and write to the SMB shared folder. Additionally, the files in the folder can be executed or be used by the installation process leading to considerable impact on confidentiality, integrity and availability. The impacted components are Crystal Report (CR) shared folder, Traditional Mobile app (attachment path), RSP (log folder logic), Job Service and BAS (file upload folder).CVSS v3 Base Score: 9,6 / 10 [CVE-2023-31403].
